Detailed Product Information

The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on rotor construction and surface treatment for direct-fit brake replacement. This rotor uses a plain disc finish with a zinc silver hat finish, while the rust resistant coating helps maintain appearance during normal brake service intervals. The nominal thickness is 25 mm, with a discard thickness of 23 mm, giving technicians the key dimensions needed for inspection and replacement decisions.

For Mazda 3 and Mazda 3 Sport front right brake rotor replacement, part number 631-80041R matches the listed fitment and hardware geometry. The 5-stud, 5-bolt layout, 14 mm stud/lug hole diameter, and 48.7 mm overall height support accurate fitment on the specified vehicles.

Common Reasons for Replacement

• Brake pulsation from rotor wear or thickness variation
• Visible scoring, grooves, or heat checking on the braking surface
• Corrosion on the rotor hat or braking area
• Reduced braking consistency during routine service
• Rotor thickness approaching discard specification

Installation Notes and Tips

Install 631-80041R only on the listed front right applications: 2004-2013 Mazda 3 and 2010-2013 Mazda 3 Sport. Confirm rotor dimensions, bolt pattern, and directional orientation before installation. Always inspect pads, caliper condition, and hub surfaces during brake service, and verify rotor thickness after installation.
